Gaining 3 kilograms (approximately 6.6 pounds) in a single day due to binge eating is highly unlikely to be solely attributed to fat gain. Such a significant weight increase in such a short period is more likely to be related to other factors, such as water retention, digestive contents, and fluctuations in glycogen stores, rather than actual fat gain.
When we consume a large amount of food in a binge episode, our bodies may retain additional water to aid in the digestion process. Also, carbohydrate-rich foods can cause an increase in glycogen stores, which bind to water molecules. These factors can contribute to temporary weight fluctuations.
However, it's important to understand that binge eating can have adverse effects on your overall health and well-being, regardless of whether it results in immediate weight gain or not. Binge eating disorder can lead to emotional distress, feelings of guilt, and may negatively impact your relationship with food and body image.
If you're concerned about your eating patterns or sudden weight changes, it's crucial to reach out to a healthcare professional or a registered dietitian who can provide personalized advice and support to help you address these issues. They can work with you to develop a healthy and sustainable approach to eating that meets your nutritional needs and supports your mental well-being.
